Is the light still on?
The tamper tab on the rear lock cylinder can fail with age and break off, telling the car someone has tried to slide-hammer your trunk lock.
I believe two doors also have tamper tabs.
My security light is on for a year now.
Disconnecting trunk cable didn't help and I don't want to disassemble door.
Sec light doesn't affect driveability so I let it stay as it is now.
